[PATCH 01/16] drm/amd/display: Refactor HPD IRQ error checking flow

[Hamza Mahfooz]

From: Leon Huang <leon.hua...@amd.com>

[Why]
HPD error status does not cover Replay desync error status
while executing autotests and CTS tests.

[How]
Refactor the checking flow, reporting the HPD error based on
different eDP feature.
